To all whom t may concern.'

` Be it known that I, FERDINAND Kino,4 subject of the King of Prussia,residing at Bahnhoftrasse, Herford, German Vhave invented certain newand useful mprovements in Safety-Razors, of which the following is aspecification.

This invention relates to certain improvements in safety razors of thetype having a thin i'exible blade, and has forits object to provide aconstruction'wherein the blade will be elestically supported near itscutting edge butheld rigid transversely, and for this purpose the bladeis clamped between two strips of' soft rubber or other elastic materialpreferably of such form that the blade is supported not over its wholesurface but only at individual points, thus enabling the cutting edveofthe blade to beni more easily longitudinally, so as to adapt itself tothe skin of the user. v i.

In order that-,the invention may be more clearly understood, referenceis made to the accompanying drawings, whereon two cm bodimentsof theinvention are illustrated by vvav of example.

lili ure l 1s a sectional view through a doub e-edgedv safety razorconstructed according to the present invention and taken substantiallyon the line AB of Fig. 3. Figr 2 is an inverted plan view ofthe upperstrip of elastic material. Fig. 3 is a plan of Fig. I with the upperelastic material, the blade and the backing removed, and Fig. 4 is aside view of the lower strip of elastic material. Fig. 5 is a sectionalview show ing the invention as applied to a single` edged safety razor.Fig. 6 is a side view of one of the strips of elastic material employedvin connection withthe razor illus-` trated in Fig. 5, and Fig. 7 is aplan view of the razor shown in Fig. 5.A A

VIn the double-'edged safety razor illustrated in Figs. l to 4t`he razorblade a is' clamped between the guard 0 and backing p between two stripsb and c of elastic material, such as soft rubber, the upper strip 7)being concave on its under side, so as to form longitudinal projectionsd onthe lower side ofthe strip. The upper sideof the strip c is formedconvex and provided with recesses c' as shown in Figs. 3 anda, thusforming convex projections f adapted to y support the razor blade a atdifferent points in its length. It will thus be seen that the blade iselastically supported longitudinally on both sides near its cutting edgeby the strips of soft rubber, while being clamped rigidly transversely.The blade is thus prevented from vibration in its holder but, at thesame time, its cutting edge is capable of adapting itself longitudinallyto the skin of the user. Moreover, the recesses e enable the cuttingedge of the blade to bend more easily longitudinally, so that it readilyadapts itself to any unevenness of the skin.-

Figs. 5, 6 and 7 illustrate the application of my invention to asingle-edged safety razor having a reversible thin blade of very' narrow dimensions. The blade g is slotted at its ends at h to receive pinse' projecting from the guard Il: so as to position the blade relaltivelyto the guard. On both sides ofthe blade g and between the backing Z andguard fl: are narrow elastic strips m of soft rubber or the like,y oneor both of which are provided with recesses n at suitable distancesapart so that the razor bladeg is only supported atindividual points inorder to enable the cutting edge of the blade to bend more readilylongitudinally while the blade is clamped rigidly transversely.
